The apfr fi automatic power factor controller presents krykard load manager series for controlling power factor from alacrity electronics, chennai. Apfr fi provides constant control on the reactive power consumed by the load and connects/disconnects capacitor banks. It is panel mountable, available in a standard 144 x 144 container with time indication duration between 2 successive capacitor step switching is adjustable from 6 to 30 seconds. The capacitor banks get automatically disconnected when supply voltage fails and the capacitor switching occurs with maximum of 14 steps. Zero-setting device for voltage failure and a filter, ensuring normal operation even in case of considerable line interference is the added feature. Technical specifications: input voltage: 110 – 220 – 380 vac ± 10 percent max power consumption: 10 va [max 20 va pfr – 12/14 max current input: 5 amp [min 250 ma] frequency: 50 hz control of cosf: between 0.8 lag to 0.9 lead control of capacitor: auto and manual mode cosf indication: between 0.7 lag to 0.98 lead by leds choice of ct input: 50/1a upto 2000/1a standard or 50/5a upto 2000/5a standard contactor [relay] rating: 5a output contact rating: 5a-250vac [100vdc]-150w-2000va [an auxiliary relay should be added if higher rating is required]. Time delay after switching off of capacitor bank to switch on: default 1 minute [lt application] optional 5 minute [ht application] environmental working conditions production degree of front panel with cover: ip 50 operating temperature range types: ht-hta max. Relative humidity: 90 percent at 20°c max. Altitude: 2000 m above sea level indoor installation away from heat sources
